Your recommendation is to stick to a pathological implementation where every page fault results in the equivalent of doing a Java GC run? All independent of the actual memory pressure? This isn't even about the exact limit, this implementation just makes no sense. Add a hysteresis at least because running this on every page fault is guaranteed to cause a lot of CPU load while not returning very much to the system.
